I, King of the Gurongi, Crush Every Rider

The protagonist transmigrates into the world of Kamen Rider Kuuga and becomes the king of the Gurongi, Unidentified Life Form No. 0, Daguba. Daguba works hard to grow stronger, so when the final battle comes, he is just a little stronger than Kuuga. He defeats Kuuga and absorbs the power in Kuuga's belt. That day, the white demon laughed maniacally, while the black angel fell silent.
